README
README.mdPSVSD 2040
This is a module based on Yinfanlu's PSVSD adapter. Last year, I took the original Eagle Autodesk files and adapted them to a KiCad EDA source. This repo code is based on my adaptation.
One of the problems with the original PSVSD is the out-of-production Genesys chip, which appears to be a generic USB-to-SD bridge that simply exposes Mass Storage. It's theoretically possible to use any such bridge chip in its place, but anyone who has read Yinfanlu's write-up on this will also know that power consumption is the main problem behind those adapters. The PS Vita's modem port never switches off power to the modem port. Therefore, these adapters consume power even when the console is off.
My own fun idea was to recreate this adapter using my favorite chip: The RP2040. It has a USB interface, fast GPIO lines, and very low power consumption---with the potential to go into deep-sleep-like states to draw very small amounts.
The main downside is USB 1.1 speeds, which theoretically cap at 1.2 MB/s.
Right now, a board has been designed and fabricated, but I have not had the time to assemble and test it. Whether this is a viable concept will remain to be seen.
Do not attempt to reproduce this unless you are fine with potentially making a faulty board that may or may not fry your PS Vita!

Questions
How big is the Psvsd PCB?
It measures 30 × 33.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psvsd use?
40 parts, built around the RP2040, W25Q32JVZPIQ, MEM2075-00-140-01-A and BM05B-SURS-TF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Psvsd KiCad files?
From the Murwnas/psvsd-2040 repository on GitHub, at the commit this page was made from: the board is psvsd.kicad_pcb and its schematic psvsd-v21_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psvsd design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
